Description

Technical Field

[0001] The present invention belongs to the technical field of heat dissipation devices, and in particular relates to an intelligent noise reduction heat dissipation device for an energy storage cabinet. Background Art

[0002] The energy storage cabinet is mainly composed of battery modules, battery management system (BMS), inverter (or converter), control system, cooling system, casing and connector. It is a device specially designed to store electrical energy. It can store electrical energy and release it for power supply when needed. It is usually used to provide backup power and stabilize grid voltage. The energy storage cabinet can smooth out the fluctuations caused by the access of non-connected new energy to the grid and maintain grid stability. At the same time, it can also suppress load jumps, play a role in frequency and voltage regulation, and improve the power factor.

[0003] As mentioned above, the energy storage cabinet contains a large number of electronic components and batteries. These components will generate a lot of heat when working. If the heat cannot be dissipated in time, the temperature inside the cabinet will continue to rise, which will affect the performance and life of the battery, and may even cause safety accidents such as fire. Therefore, it is crucial to effectively dissipate the heat of the energy storage cabinet, so each energy storage cabinet must have a fan. Secondly, with the rapid development of energy storage technology, the energy and power density of energy storage systems are constantly improving, which makes energy storage temperature control an unavoidable topic. Under the condition of meeting the large-scale deployment of battery cells, how to efficiently dissipate heat to ensure the safety of the energy storage system has become an urgent problem to be solved.

[0004] In addition, the energy storage cabinet will generate certain noise during operation, which mainly comes from key components such as motor drive, cooling system, inverter and transformer. These components will inevitably produce vibration during operation, and this vibration is the source of noise. In densely populated areas, these noises may exceed the legal standards, causing trouble to residents and even causing complaints and disputes. Therefore, it is also necessary to reduce the noise of the energy storage cabinet.

[0005] Therefore, how to achieve noise reduction and heat dissipation without increasing the amount of noise-generating electrical equipment is currently a topic that needs to be studied and optimized. Summary of the invention

[0006] In view of the problems raised by the above background technology, the purpose of the present invention is to provide an intelligent noise reduction and heat dissipation device for an energy storage cabinet.

[0007] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0008] An intelligent noise reduction and heat dissipation device for an energy storage cabinet, comprising a cabinet body and an outer cabinet installed on the outside of the cabinet body, the cabinet body being provided with heat dissipation holes on the left and right sides, a fan being installed on the top of the cabinet body, a water tank being installed on the top of the outer cabinet, a filter being installed on the water tank, a water supply pipe being connected to the output end of the water tank, a first one-way valve being installed on the output end of the water supply pipe, a rebound airbag being connected to the output end of the water supply pipe, the rebound airbag being located between the outer bottom of the cabinet body and the inner bottom of the outer cabinet, the output end of the rebound airbag being connected to the water supply pipe, a second one-way valve being installed on the input end of the water supply pipe, a velvet pad being installed between the outer bottom of the cabinet body and the inner bottom of the outer cabinet, and the velvet pad being horizontally placed on both sides of the rebound airbag;

[0009] A liquid cavity is provided in the cabinet wall of the outer cabinet, the output end of the water supply pipe is connected to the liquid cavity, the outer cabinet is provided with a heat dissipation pipe, the position and number of the heat dissipation pipe correspond to the heat dissipation holes, an overflow hole is provided at the bottom of the heat dissipation pipe, a through slot is provided at the top of the liquid cavity, and the position and specification of the through slot correspond to the fan.

[0010] It is further defined that the cabinet body is provided with a wire hole, and the outer cabinet is provided with a wire tube whose position corresponds to the wire hole. Such a design is conducive to wiring.

[0011] It is further defined that the bottom of the water tank is in a conical shape inclined toward the output end. Such a design is conducive to the collection and aggregation of liquid.

[0012] It is further defined that the water tank is detachably mounted on the top of the outer cabinet, and such a design facilitates disassembly for cleaning and replacement.

[0013] It is further defined that a sound insulation board is filled and installed between the outer peripheral side of the cabinet body and the inner wall of the outer cabinet. Such a design fixes the position of the cabinet body and enhances the sound insulation effect at the same time.

[0014] It is further defined that the velvet pad has multiple specifications, and each specification of the velvet pad is fixedly installed on the bottom of the outer cabinet. Such a design can be adapted for installation on cabinets of different heights, and velvet pads of different heights can also control the compression strength of the cabinet on the rebound airbag.

[0015] It is further defined that a spring steel coil is installed inside the rebound airbag, and such a design ensures the rebound strength and rebound life.

[0016] It is further defined that the outer cabinet is provided with an inclined baffle at the top of the port of the heat dissipation pipe. Such a design prevents debris from entering the interior of the cabinet through the heat dissipation hole from the heat dissipation pipe.

[0017] It is further defined that the cross-section of the rebound airbag is circular, and a plurality of the rebound airbags may be provided and connected. Such a design ensures the supporting effect for the cabinet while ensuring the absorption of the vibration generated by the operation of the cabinet. The connection of a plurality of rebound airbags can increase the displacement.

[0018] It is further defined that the liquid cavity is provided with a gas-liquid separation net on the peripheral side of the through slot. Such a design prevents water vapor from affecting the service life of components inside the cabinet.

[0019] The beneficial effects of the present invention are as follows:

[0020] By adopting the structural design of the present invention, no power components are added to the cabinet and its matching heat dissipation device, so no redundant energy is consumed, and further, no noise generation source and heat generation source are added;

[0021] The present invention collects rainwater and the vibrations that are bound to be generated when the cabinet is running to discharge rainwater into the liquid cavity, and utilizes the characteristics of the liquid to achieve the effect of sound insulation and noise reduction. Moreover, because the cabinet is sealed inside, the wind force required to be extracted when the fan is running will be extracted from the liquid cavity, and the temperature of the wind passing through the water is generally lower, so the effect of cooling and heat dissipation is achieved.

[0032] A liquid cavity 13 is provided in the cabinet wall of the outer cabinet 2, and the output end of the water supply pipe 10 is connected to the liquid cavity 13. The outer cabinet 2 is provided with a heat dissipation pipe 14, and the position and number of the heat dissipation pipe 14 correspond to the heat dissipation holes 3. An overflow hole 15 is provided at the bottom of the heat dissipation pipe 14, and a through slot 16 is provided at the top of the liquid cavity 13. The position and specification of the through slot 16 are symmetrical with the fan 4.

[0033] Preferably, the cabinet body 1 is provided with a wire hole 17, and the outer cabinet 2 is provided with a wire tube 18 whose position corresponds to the wire hole 17. Such a design is conducive to wiring. In fact, wiring measures can also be considered according to specific circumstances.

[0034] Preferably, the bottom of the water tank 5 is in a conical shape inclined toward the output end. Such a design is conducive to the collection and aggregation of liquid. In fact, the structural shape of the bottom of the water tank 5 can also be considered according to specific circumstances.

[0035] Preferably, the water tank 5 is detachably mounted on the top of the outer cabinet 2. Such a design facilitates disassembly for cleaning and replacement. In fact, the installation measures of the water tank 5 can also be considered according to specific circumstances.

[0036] Preferably, a sound insulation board is installed between the outer peripheral side of the cabinet body 1 and the inner wall of the outer cabinet 2. Such a design fixes the position of the cabinet body 1 while enhancing the sound insulation effect. In fact, the material and thickness of the sound insulation board can also be considered according to specific circumstances.

[0037] Preferably, the velvet pad 12 has multiple specifications, and each specification of the velvet pad 12 is fixedly installed on the bottom of the outer cabinet 2. Such a design can be adapted for installation on cabinets 1 of different heights, and the velvet pads 12 of different heights can also control the compression strength of the cabinet 1 on the rebound airbag 9. In fact, the specifications of the velvet pad 12 can also be customized according to specific circumstances.

[0038] Preferably, a spring steel ring is installed inside the rebound airbag 9. Such a design ensures the rebound strength and rebound life. In fact, the selection of the rebound airbag 9 can also be considered according to specific circumstances.

[0039] Preferably, the outer cabinet 2 is provided with an inclined baffle 19 at the top of the port of the heat dissipation pipe 14. Such a design prevents debris from entering the cabinet 1 through the heat dissipation hole 3 from the heat dissipation pipe 14. In fact, protective measures may also be considered according to specific circumstances.

[0040] Preferably, the cross-section of the rebound airbag 9 is circular, and multiple rebound airbags 9 can be set up and connected. Such a design ensures the supporting effect of the cabinet 1 while ensuring the absorption of the vibration generated by the operation of the cabinet 1. The connection of multiple rebound airbags 9 can increase the displacement. In fact, the specifications and quantity of the rebound airbags 9 can also be selected according to specific circumstances.

[0041] Preferably, the liquid chamber 13 is provided with a gas-liquid separation net 20 around the through slot 16. Such a design prevents water vapor from affecting the service life of components inside the cabinet 1. In fact, measures to prevent water vapor from interfering with operation may also be considered according to specific circumstances.

[0042] In this implementation case, when using an intelligent noise reduction and heat dissipation device for an energy storage cabinet, the door of the outer cabinet 2 is opened, and the cabinet body 1 is placed in the outer cabinet 2. The split structure is conducive to the separate production of the outer cabinet 2 and the cabinet body 1 and the use of the vibration generated by the operation of the cabinet body 1, and it is also convenient to take out during maintenance. Then, a sound insulation board or filler is installed on the surrounding side of the cabinet body 1 to prevent the cabinet body 1 from moving in the left and right directions. If the outer cabinet 2 is set to match the cabinet body 1, the sizes of the left and right sides are adapted and no filler needs to be installed. Then, the thickness of the velvet pad 12 is installed. The thickness of the velvet pad 12 is selected so that when the cabinet body 1 is placed in the outer cabinet 2, the distance between the upper side of the cabinet body 1 and the outer cabinet 2 is 0.5 to 1 cm. Then, under normal conditions, the horizontal position of the highest point of the rebound airbag 9 is 0.5 to 1 cm higher than the highest horizontal plane of the velvet pad 12.

[0043] During operation, the cabinet 1 vibrates. Under this vibration, the rebound airbag 9 is repeatedly compressed with a slight or even small amplitude. Under this compression and the flow limitation of the first one-way valve 8 and the second one-way valve 11, the liquid in the water supply pipe 7 is delivered to the liquid cavity 13 through the water supply pipe 10 bit by bit. This water delivery method is used to control the water level in the liquid cavity 13, and water delivery is only started when the outer cabinet 2 is in operation to prevent excessive waste of water resources. Because the source of water for this device mainly comes from rainwater, if water is added manually regularly, water can be directly added to the liquid cavity 13. When the water level in the liquid cavity 13 reaches the position of the heat dissipation pipe 14, it is discharged from the heat dissipation pipe 14 through the overflow hole 15;

[0044] Because there is water in the liquid cavity 13, and when the fan 4 of the cabinet 1 is running, the extracted wind force only comes from the liquid cavity 13, so the extracted wind force has the temperature of the water, which is conducive to cooling, thereby achieving the purpose of accelerating heat dissipation, and the liquid cavity 13 acts as a medium to disperse and eliminate the noise generated by the operation inside the cabinet 1, thereby achieving the purpose of noise reduction.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
